If a couple mutually plans to never consummate their marriage, would this make the marriage invalid from the beginning? And if so, what if they make this mutual decision after they are validly married? (i.e., had the intention of consummating when they took their vows)
I'm thinking the answer is no, because Mary and Joseph were validly married, and yet never consummated their marriage. I think the only thing that matters is the ability to engage in the "marriage act", right? Impotence is an impediment, but not intentional abstinence, correct?
An unconsummated marriage is valid, but dissolvable by the pope.
A couple that plan to have a Josephite marriage must have permission to do so. When they marry, they agree to the exchange of the right to intercourse. So, if at any point in the marriage one or the other party wishes to cease the Josephite marriage and begin conjugal relations, the other party must be prepared to do so.
You are corrrect, impotence is an impediment. The ability to have intercourse must be present. They can choose to be continent for a time or permanently. But, again, if either party wants to take up all the duties of marriage, the other must do so.
